Which statement is true about the graphs of the two lines y is equal to negative 4 fifths x plus 2 and y is equal to negative 5 fourths x minus 1 half ?

In slope-intercept form, the slopes are −4/5 and −5/4. Perpendicular lines have slopes that are negative reciprocals, so their product must be −1; here the product is (−4/5)(−5/4) = 1. The slopes are also unequal, so the lines are not parallel. Thus, they are neither parallel nor perpendicular, as stated in choice A.
